5. in output terminal formula protection power source, adjustment triode used is high back-pressure high power valve, and luminotron is high brightness type luminotron.

For having a clear understanding of the meaning of the technical program, at first will make the following instructions:

The inventor has done to study for a long period of time to anti-theft safety door, and anti-theft safety door has arrived the stage of following progress:

The firstth, normal door is opened the door without mechanical key, but the mode of opening the door with electronics telecontrol engineering or phone.When normal door, be installed on the propulsion system in door, will promote the lockset action, realize opening the door.Meanwhile, still retained the form that mechanical key opens the door, its objective is and when automatic system goes wrong, can have a kind of opening the door to make up.This be if open the door with mechanical key, and great majority are to want to be also the situation that needs telephone call by joining the situation of mechanical key crime.And a few cases is own because electrical equipment goes wrong, oneself to want the situation of opening the door with mechanical key, but this situation is own clearly situation on the scene, produces alert sound oneself and does not also feel fearful and nervous.

The secondth, there is identification circuit, can correctly identify is the situation of crime behavior or owner's normal door.Its reason is that the behavior of opening the door normally is to open the door by electronic technology, rather than opens the door with mechanical key.When normal method is used electronic open-door, the identification circuit input has electronic signal, and the input of crime behavior identification circuit will start warning system without electronic signal.

For this reason, the existing meaning to each technical measures of the present invention, concrete condition further is explained as follows:

The switch of one, pacifying in measure scheme one, be the key component that warning of the present invention starts, and is also a bright spot of the present invention, because after the existing achievement of this part and inventor cooperatively interacts, warning of the present invention having been accomplished more scientific, is also the place different from a lot of alarms, and its reason is:

The one, can generation not make us terrified wrong report, this is the most important.Its reason is, the use ' key ' that owner is absent from the scene is within doors opened the door by lockhole, is the crime behavior, and warning now is very significant.

The 2nd, very reliable, because, the opening the door at closing time of normal life, do not need artificial additional move, do not affect the normal habits and customs of people, thereby do not affect the normal operation of the each starting of security system.

The 3rd, protection is tight, is no matter to force open the door or the perpetrator wants to get started by cracking lockhole by barbarous mode, all can produce warning.

The 4th, the warning starting switch is sensitive and reliable, can when the crime behavior is not accomplished, just not report to the police, thereby loss is reduced to minimum.The initiating signal of reporting to the police because the switch contact when lockhole cap is becoming flexible on lockhole will change.

Two,Be positioned on the warning starting in door, with being placed on telephone call within doors, adopt wireless remote control to contact, so telephone call is laid a little arbitrarily, strengthened confidentiality.

Three, dialing integrated circuit chip in the present invention in the information processing part is following function, the one, can store a plurality of telephone numbers, in the situation that oneself stores complete in advance, (the present invention can utilize former existing phone to be stored this integrated circuit), as long as being stored to pin, it adds a trigger pip, this sheet will automatically be controlled and send a phone number dial, so its a plurality of storage number ends have been connected on respectively on a plurality of output terminals in a sequential circuit cell, the dialing output terminal of this integrated circuit has been connected on telephone set, so when the starting telephone call, the multi-section telephone number that a plurality of output terminals of programme control circut can start this element storage outwards dials.The models of a lot of dialing integrated circuit have powerful storage number function, and a lot of integrated circuit storage capability are all at 10 more than number, so telephone alarm function is very powerful.

Four, the program circuit in this unit can consist of a variety of circuits, and the Copper Foil that its first output terminal is corresponding with the Hands-free key of telephone set in this part is connected, and other output is stored pin with the multidigit in the dialing integrated circuit respectively and is connected.The program control rule formed is that at first the first output export the Hands-free key of the high-order support machine that puts telephone lines into operation, and produces the off-hook program, then trigger the first storage number pin in the dialing integrated circuit chip; Call out the conversation of First receiver; As method repeatedly, can call out all receiver numbers that this sheet is stored.

Five, owing to having adopted in technical scheme one, report to the police to start, the two-part combination closely of telephone call, just formed such defence program and protection philosophy, when normal the anti-theft security door knob other people keep outside the door.When having the people to force open the door by barbarous mode, when door separates with doorframe, be loaded on door and change and produce alerting signal with the travel switch contact of doorframe junction; When committing a crime by lockhole, once open lockhole cap, be loaded between locking closure and door can be because become non-oppression state from oppression state without self-locking button switch, will become the signalling state without the normally closed contact of self-locking type pushbutton switch; Identification of lines through this bright person in being fruitful, conclude whether this warning.If belong to, report to the police, can produce two functions, a kind of function is to connect to promote alert acoustic-electric source, produces onsite alarming, and warning is caused in scene, prior a kind of function is to be positioned on the controlled emissions plate radiating circuit starting of antitheft door part, after the reception dress is received and is transmitted, the warning that produces the multi-section phone, the owner of notice mobile phone, determine in time, with processing.Loss is reduced to minimum, or made up.

Six, power supply is an emphasis of the present invention, is directly connected to performance of the present invention.The specific explanations of circuit is as follows:

1, the cardinal principle of voltage stabilizing:

Adjust triode and adopted and penetrates with output, very strong negative feedback is arranged, once after line parameter circuit value determines, adjusting triode just can be stabilized on a concrete numerical value, and can meet the requirement of equipment, if it is less to adjust the upper inclined to one side resistive arrangement of triode, its with power also very large.

2, the reason that there is good anti-lightning effect: when thunderbolt is arranged, usually that power supply is perishable the time, as common household electrical appliances, be that take the to cut off the power supply mode in source is avoided, but the specialities as security personnel's class, as resolute power down source will become security personnel's blank, so improving lightning protection effect is an emphasis of the present invention, the present invention has taked following some effective measure for this reason.

The first, adopt active controllable silicon to form " fast tripping protection function ", excellent performance, have very strong lightning protection overvoltage capabilities.

This element is (111) the part controllable silicon in accompanying drawing 1, and the peripheral part that triggers: stabilivolt (110), resistance R 4(109).The principle formed is: if thunderbolt and while causing output terminal too high and after surpassing the door of diac; silicon controlled trigger element stabilivolt (110) conducting; thereby triggering controllable silicon (111) conducting; immediately to adjusting the base stage short circuit of triode (103); cause and be closed adjusting triode (103) output voltage, form lightning protection overvoltage fast tripping protection.Why being called " fast tripping protection ", is because too high once output terminal, and controllable silicon leads that (111) are logical has a very strong positive feedback, can will adjust the base stage short circuit of triode (103) rapidly, forms " fast tripping protection function ".And, after output is normal, after can not puncturing controllable silicon (111) with no pressure, controllable silicon anode dead electricity, recover automatically, if again be struck by lightning, again start, form protection, until output voltage is normal value.

The second, " the fast tripping protection function " of this active formation in " open-circuit condition ", just works while needing only thunderbolt or overvoltage when work, thus be not easy to damage, constantly all in a kind of guard mode.

Its reason is power output end while being normal condition, and controllable silicon, in off state, does not have " electrical wear ", can not damage.And its external trigger is enclosed part stabilivolt voltage stabilizing value higher than output end voltage, so in open-circuit condition, there is no " electrical wear ", can not damage yet yet, at any time all can be in a kind of " armed state ".

Three, adjusting triode is high inverse-voltage tube, and lightning protection effect is good.

Its reason is, this pipe oppositely suctions through voltage usually at hundreds of volts, and 78 serial back-pressures are generally 30 volts.Than 78 series commonly used, to exceed more than 10 times.

Four, be equipped with anti-thunder tube, this pipe voltage breakdown is tens of volts, after high inverse-voltage tube coordinates, thereby has very large surplus.

3, form the overcurrent protection principle: when output current is excessive; the resistance R 3(that the adjustment transistor emitter is connected is overcurrent protection resistance) the pressure drop increase; while surpassing certain value; diode current flow in the overcurrent protection branch road; flow into output voltage and adjust the base current minimizing of triode; load overcurrent is super many, and the base current reduced is more, automatically forms adjusting the triode protection.

4, can produce meaning and the reason of overcurrent protection indication: general device breaks down; overcurrent condition accounts for significant proportion; particularly when overvoltage active impaired the time, and overcurrent must react on power supply, so be accurately using power supply as monitoring point.If it is also that positive effect is arranged that overcurrent has demonstration, because one have demonstration, show that this equipment or instrument have fault, both carried out " Rough Inspection ", improved maintenance efficiency.The reason that can realize the overcurrent indication is; during overcurrent; the base flow shunting of adjusting triode will be flow through light emitting diode; lamp is bright; so this diode is complex function, the one, utilize its function that has PN economize on electricity to press, allow it with after overcurrent protection resistance R 3 coordinates with it; realize overcurrent protection, the 2nd, utilize its luminescent properties to realize the overcurrent indication.

5, at civil power, higher place and the period can not damaged the reason of circuit: because adjusting triode, be high inverse-voltage tube, although the voltage of now bridge-type output is high, and also can be far below the high inverse-voltage tube withstand voltage.

The main cause of place that 6, can be lower at civil power and period work: the one, the adjustment triode in circuit, can not produce the additional electrical pressure drop.(illustrate: if the raising input voltage scheme that adopts traditional triode to connect with three end integrated circuit, for triode and three ends can be worked, the one, give the voltage of three end integrated circuit input ends higher than output terminal, the 2nd, the operating voltage that need to triode, main product has been given birth to triode supplementary loss voltage like this, and, when civil power is low, this is valuable voltage.) it two is to be high inverse-voltage tube because adjusting triode, so can design the bridge-type output voltage higherly when design, when civil power is low, at this moment bridge-type voltage can not be very low, just can do certain compensation.

7, can expand the reason of civil power variation range: due to upper two reasons, do not damage circuit when civil power is high, and still can work when low.So can expand widely the working range that civil power changes.

8, can adjust the reason of different output voltage stabilizing values.In reference voltage the first branch road, the pressure drop of stabilivolt is leading role, so can form coarse adjustment, and the shared ratio of the resistance R 2 of going here and there is very little, so also can do the use of accurate adjustment, the benefit of accurate adjustment is can the furnishing normal voltage required to the accumulator floating charge, as 6.6 volts; 12.8 volt etc.

After the invention process, the anti-theft security goalkeeper presents a kind of brand-new looks, and following outstanding advantage is arranged:

1, after the invention process; anti-theft safety door and alarm have been realized the combination of science; the advantage that has possessed two kinds of protectors; usually both can keep the people outside the door; when running into other people and committing a crime; can send two kinds of warnings; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will suppress the crime behavior generation; and whether waiting for passively its destruction) be all very significant, the situation of the passive defence of anti-theft safety door so this product is through with fully, promoted security personnel's performance of anti-theft safety door all sidedly.

2, the warning system partial properties is very excellent, for alarm, is most valuable, embodies in the following areas:

The one, warning system can not reported by mistake fully.Because after existing achievement coordinates, there is automatic recognition property.The warning produced when owner is absent from the scene may be only the crime behavior.Otherwise the behavior of not committing a crime, the warning starting switch can not send signal, at this moment because the structures shape of switch is installed.Due to the intrinsic property of switch, the variation of contact when being subject to compressing and not suffering oppression, shift knob occurs to occur.

The 2nd, reliable, its reason one is, the user is closing the door when opening without any need for other additional move, thereby warning system is at any time all in a kind of " highly waiting " state, do not need any preliminary work, the 2nd, the malfunctioning chance of mechanical switch can be far superior to electronic component.

The 3rd, easy to use.Do not affect normal habits and customs after installation fully.If increased trouble with former life, the shortcoming of obviously bringing to the people is or is to use inconvenience, or forgotten necessary operation and bring the malfunction of warning or malfunctioning.

The 4th, on-the-spot and two kinds of warnings of phone are arranged, deterrent force is larger, used because both complementations respectively have.

3, single also have following characteristic with regard to telephone call:

One of be the warning great efforts, can store the multi-section phone, send out mass-sending simultaneously, such benefit one is to carry out Advise By Wire to a plurality of personnel, the 2nd, both can call out the mobile phone of taking with oneself generation, can call out the fixed line phone in relevant place again, can, to the various objective factors that are unfavorable for Advise By Wire, reducing to minimum, stop even fully.

Two be that called out multi-section phone all can be known, the limitation of having stopped to only have a people to know with may be errorless.

Three persons that are the acknowledge(ment) signal can hear language or the alert sound of warning, and can listen to scene.

Four be easy production, the one because report to the police part and telephone set unification, can save many circuit, as general off-hook element circuit, store the keypad of number etc., and the part increased is very limited, the 2nd, element used all belongs to part commonly used.

Five, can accomplish a tractor serves several purposes, the telephone set after repacking, be a kind of telephone alarm, but still retained all properties of telephone set, still can be used as communication telephones, such largest benefit is that family does not have too much device ornaments and to affect family attractive in appearance.

4, supporting power source performance is good, shows following several respects:

(1), anti-thunder and overvoltage protective property excellence.The one, because " fast tripping protection " that this protection circuit forms is highly sensitive, because controllable silicon has very strong positive feedback ability, once output end voltage is too high, surpass the diac threshold voltage, controllable silicon moves immediately.The 2nd, protection is large, because immediately output end voltage is clamped substantially to zero after controlled silicon conducting; The 3rd, there is automatic protection and auto restore facility, thereby protection system all the time in Status of Backups, do not produce electrical wear when overvoltage not, its largest benefit is unexpected few, reliability is high.Because overvoltage protective property is good, so, when thunderbolt, the equipment damage probability is few, can cut off the power supply.This is even more important for a lot of specialities.

(2), with common source of stable pressure, compare, the present invention has monitoring function, when overcurrent appears in circuit, the indication of LED light is arranged.Can find rapidly the damage equipment in the multilevel signal amplifying circuit like this, improve maintenance efficiency, the present invention can monitor at any time and understand set standby duty, has improved reliability.

(3), adapt to widely, than traditional stabilized voltage supply, wider adaptive faculty is arranged, be can make local work that joined electrical equipment is high at voltage and unlikely damage, and lower place and the period also can work at voltage.

(4), can be used for output generation the voltage stabilizing value of decimal arranged, be convenient to the floating charge of accumulator science.The 4th,, excellent performance, there is over-voltage over-current protection.Be fruitful supporting after, there is good performance.And be difficult to realize by the co-design of three traditional end integrated circuit or traditional triode and three end integrated circuit.So the present invention has very strong ability to provide the auxiliary items, also can be supporting with other electronic products.

(5), the cost of the co-design of cost and traditional triode and three end integrated circuit, substantially do not increase, and cheap more a lot of than a lot of professional stabilized voltage supplys.

(6), simple in circuits, easily produce and debugging, reason one is because the debug point in circuit is few, and parameter is consistent, the 2nd, after the debugging of protection system adopts the diode series connection, suitable batch.
